Multi-gas Analyzer NMA-250
Multi-gas analyzer NMA-250 is a portable analyzer designed for measurement, analysis, monitoring and control of gas output. Equipped with four gas detector sensors for oxygen, combustibles, hydrogen sulfide and carbon monoxide. The Acrylonitrile- Butadiene- Styrene body shell is temperature-chemical resistant and durable at low temperatures.
